A blood test for prolactin content: why and when is it done, and how to prepare for it?
Conducting a test to determine the concentration of prolactin in a woman’s body is a very important procedure. It helps to detect abnormalities in the organs of the reproductive and endocrine systems, as well as to determine their causes.
Like any other diagnostic procedure, this study requires careful preparation. For this reason, it is important to know how to properly deliver the biomaterial for research on prolactin, under what circumstances it is necessary, and what should be done to avoid distortion of the data analysis.

- When is the test performed?
- Features of preparation for the procedure
- How to behave on the day of delivery of the analysis for prolactin?
To begin with, let's look at why a prolactin test is taken and who is shown to perform this test.to contents ↑
Why do we need analysis?
Prolactin is also called the female stress hormone, which is produced by the brain's pituitary cells. He is responsible for the full-fledged work of the reproductive sphere of a woman, but, in addition, it also has a great influence on the work of the endocrine system. To donate blood for research on the determination of prolactin content is necessary in order to:
- identify pathologies of an autoimmune nature;
- to determine the causes of inability to get pregnant;
- determine the factors that entailed pathological changes in the structure of the mammary glands, etc.
As for when to pass a biomaterial to determine the level of the hormone prolactin, among the indications should be noted, first of all, the following abnormalities:
- frequent changes in menstrualcycle;
- development of mastopathy with all its attendant abnormalities: vision problems, migraines, etc.;
- presence of milk-like secretions from the mammary glands;
- sharp and significant weight gain;
- unreasonable breast augmentation, its soreness and increased sensitivity;
- reduced milk production in a nursing mother.
These are cases where it is imperative to take an analysis of prolactin, since the above abnormalities may be the result of more serious problems in the functioning of the woman's body. Therefore, it is better not to let the situation take its course, but to immediately identify the causes of the anomaly and eliminate them without health consequences.to contents ↑
When does the test run?
Now let's consider the question on which day of the cycle it is possible to take the biomaterial for prolactin. In principle, venous blood can be collected on any day, and the menstrual cycle is not important in this situation.
Although, of course, there are exceptions. If we are talking about when to be tested for prolactin to the mother, who recently only completed the breastfeeding process, the interval between the last feeding and the blood donation should be at least 7-10 days.

What are the symptoms that indicate an increase in prolactin levels and how dangerous is this?
of when, and on what day of the cycle, to give prolactin in order to obtain reliable data. Of course, it is better to wait until the menstruation begins to set in on the previous schedule - then it will be possible to determine the most optimal time to visit the laboratory and donate the biomaterial.for contents ↑
Features of preparation for the procedure
By the process of testing for the determination of the concentration of prolactin, preliminary preparation is necessary, which involves the following simple steps:
- 24 hours before the test, you should not be very active in physical terms. Excessive loads can cause distortion of the test results.
- Exclude sex before and on the day of analysis. The release into the blood of sex hormones and the so-called "hormones of happiness" causes a jump in the prolactin indices and their increase several times.
- A woman needs to wear soft underwear 1 day before the test, which will not irritate or stimulate the areola of the mammary glands.
- Refuse thermal procedures( hot showers or baths, going to the sauna, etc.), since high temperatures can also affect the reliability of the research data.
Donating a biomaterial for clinical analysis of prolactin is better on an empty stomach. Therefore, in the evening you should eliminate the use of heavy food. But this does not mean that supper should be excluded - let it just be light, not burdened with high-calorie, carbohydrate products.
You can make a light vegetable stew or salad. However, remember that the interval between dinner and the process of venous blood sampling should not be less than 9 hours.
Preparing for blood donation for a prolactin test also requires a good night’s rest. Having come to the clinic tired, the patient runs the risk of receiving inaccurate test data.to contents ↑
How to behave on the day of delivery of prolactin analysis?
Having understood which day of the cycle the prolactin biomaterial is usually donated to, and how to prepare for this process, it is necessary to consider in detail how the patient should behave just before the manipulation. This also plays an important role, since many factors can have a direct impact on the test results. And these factors must be excluded.
First of all, it is necessary to pass an analysis to determine the concentration of prolactin in a state of absolute physical and moral relaxation. That is, the patient must be absolutely calm, because strong emotions can lead to a jump in the stress hormone.
To obtain accurate results, you need to go to the clinic in the range of 8-11 am, while you need to get up at least 2-3 hours before traveling to a medical facility.
Important! Donating biological material to determine prolactin is necessary only on an empty stomach! On the day of diagnostic manipulation it is necessary to exclude even tea, coffee and juice.
Smoking women should refrain from smoking cigarettes a few hours before the clinical procedure. When you come to the laboratory, you should sit down and rest for 20-30 minutes. As already noted, with intense physical exertion, a large number of hormones are released, so you need to wait a bit until their concentration returns to normal.
If you follow these recommendations, it is easy to donate prolactin correctly. The increased and decreased levels of this substance are a serious deviation, and if one takes into account the fact that it is influenced by many factors( pregnancy, age, environment, psychological state, etc.), then it is necessary to prepare for the analysis carefully.
Do not neglect any of the above recommendations to avoid having to retake the test. After all, if there are abnormalities in the body, delay in diagnosis and treatment can have unpleasant consequences.
